APD to monitor air quality in Mangaluru during Diwali

Mangaluru, Jul 17: Dakshina Kannada district Youth Congress president Mithun Rai has tested positive for the covid-19. 

Mr Rai took to social media to announce it: “I have been tested COVID19 positive & I am under Quarantine at Bangalore. With all your love and blessings, I will recover and be back soon at your service.

“My request to all those who were in close proximity with me in the last few days, kindly get yourselves checked for COVID,” he stated in a social media post on Friday.

Washington D.C., May 8: The prime time for brain development in a child's life is the first year, where the infant spends most of the time asleep. It is the time when neural connections form and sensory memories are encoded.

However, when sleep is disrupted, as occurs more often among children with autism, brain development may be affected, too.

New research led by the University of Washington finds that sleep problems in a baby's first 12 months may not only precede an autism diagnosis but also may be associated with altered growth trajectory in a key part of the brain, the hippocampus.

The study, which was published in the American Journal of Psychiatry, researchers report that in a sample of more than 400 taken of 6- to 12-month-old infants, those who were later diagnosed with autism were more likely to have had difficulty falling asleep.

It also states that this sleep difficulty was associated with altered growth trajectories in the hippocampus.

"The hippocampus is critical for learning and memory, and changes in the size of the hippocampus have been associated with poor sleep in adults and older children.

As many as 80 per cent of the children with autism spectrum disorder have sleep problems," said Annette Estes, director of the UW Autism Center and senior author of the study.

"In our clinical experience, parents have a lot of concerns about their children's sleep, and in our work on early autism intervention, we observed that sleep problems were holding children and families back," added Estes, who is also a UW professor of speech and hearing sciences.

"It could be that altered sleep is part-and-parcel of autism for some children. One clue is that behavioural interventions to improve sleep don't work for all children with autism, even when their parents are doing everything just right. This suggests that there may be a biological component to sleep problems for some children with autism," said Estes.

To consider links among sleep, brain development, and autism, researchers at the IBIS Network looked at MRI scans of 432 infants, surveyed parents about sleep patterns, and measured cognitive functioning using a standardized assessment.

At the outset of the study, infants were classified according to their risk for developing autism: Those who were at higher risk of developing autism -- about two-thirds of the study sample -- had an older sibling who had already been diagnosed.

Infant siblings of children with autism have a 20 per cent chance of developing autism spectrum disorder -- a much higher risk than children in the general population.

In the current study, 127 of the 432 infants were identified as "low risk" at the time the MRI scans were taken because they had no family history of autism.

They later evaluated all the participants at 24 months of age to determine whether they had developed autism. Of the roughly 300 children originally considered "high familial risk," 71 were diagnosed with autism spectrum disorder at that age.

Problems with sleep were more common among the infants later diagnosed with an autism spectrum disorder, as were larger hippocampi. No other subcortical brain structures were affected, including the amygdala, which is responsible for certain emotions and aspects of memory, or the thalamus, a signal transmitter from the spinal cord to the cerebral cortex.

The authors note that while parents reported more sleep difficulties among infants who developed autism compared to those who did not, the differences were very subtle and only observed when looking at group averages across hundreds of infants.

Sleep patterns in the first years of life change rapidly as infants transition from sleeping around the clock to a more adult-like sleep/wake cycle. Until further research is completed, Estes said, it is not possible to interpret challenges with sleep as an early sign of increased risk for autism.

Varanasi, Jan 20: An FIR has been lodged against unidentified persons for a controversial hoarding near the Varanasi railway station. It is worth mentioning here that Prime Minister Narendra Modi himself is the MP of Varanasi Lok Sabha constituency.

The hoarding near the Englishiya Line crossing read, "Hindu dharma mein ghar vapasi karo... CAA, NRC se chhutkara pao (Get rid of CAA, NRC by converting to Hinduism)".

Inspector Ashutosh Ojha said that the FIR under section 295 A and 505 of IPC has been lodged.

"Investigation has been launched in the case and those involved in putting up the hoarding would be identified soon," he added.

According to sources, a lesser known outfit, Hindu Samaj Party, had placed the hoarding on the busy road.

The outfit's state Vice President Roshan Pandey had made a video viral on social media with his message in which he claimed to have put up the hoarding in response to the protest being staged at Shaheen Bagh, New Delhi.

The hoarding, which also has photographs of some Muslim women wearing saffron pagdi, was removed by the police late Saturday evening.

It came up at a time when Chief Minister Yogi Adityanath, Union Minister Smriti Irani and other leaders were in Varanasi to address a rally in support of the Citizenship Amendment Act at the Sampurnanand Sanskrit University.

Pandey, along with his supporters, had also tried to stage a sit-in at Lanka to give a call for marching to Shaheen Bagh in Delhi but was prevented by the police.

They were taken in custody and were later released following initial interrogation, said inspector Lanka, Bharat Bhushan.
